4 3.02 EXAMINATION A. Site Verification of Condition: 1. Verify that site conditions are acceptable for application of the waterproofing system. 2. Do not proceed with application until unacceptable conditions are corrected PREPARATION A. Surface Preparation: 1. Ensure that the surfaces to receive waterproofing are structurally sound and free of moisture, dust, mud, loose mortar, fins, metal projections or any substances that would be detrimental to the bonding of the membrane to the surface. 2. Remove wall ties. 3. Patch cracks, voids and holes with nonshrink grout or mastic. Specifier Note: Coordinate article below with manufacturer s recommended application requirements APPLICATION A. For vertical application [Spray] [Brush] [Roll] [Trowel] apply a uniform coat of waterproofing to entire wall area. Obtain a seamless membrane free of entrapped gasses, with a minimum dry film thickness of 80 mil (2 mm) at 10 feet (3.1 m) below-grade wall application, 100 mil (2.5 mm) at 20 feet (6.1 m) below-grade wall application and 120 mil (3 mm) at 30 feet (9.2 m) or more for below-grade wall application. 1. Apply fluid membrane onto footing area a minimum of 4 inches (102 mm) to prevent water pooling. 2. Allow membrane to cure for 24 hours before placing any backfill against the wall. 3. Follow the current installation instructions. B. For horizontal application [Spray] [Brush] [Roll] apply a uniform coat of waterproofing to entire wall area. Obtain a seamless membrane free of entrapped gasses, with a minimum dry film thickness of 100 mil (2.5 mm) for Above/At grade application. 1. Allow the fluid membrane to cure out approximately 3-4 hours. 2. Fluid membrane will still be tacky. 3. Install ArmorDrain 400 Draincore following current installation instructions INSULATING/DRAINAGE BOARD/ROLL INSTALLATION Specifier Note: Edit, retain or delete paragraphs below to comply with project requirements and specifier practices. A. When using Geo-Mat Plus roll, install after membrane has been applied. Place and secure to substrate according to manufacturer s current written instructions. 1. While the membrane is still tacky, begin installation at a corner. Install horizontally against the waterproofing membrane with the polypropylene geotextile mat side facing out-ward. 2. Install panels from top of footing extending to finish grade level. If there is overlapping off the membrane once you have reached the grade line, a utility knife or similar tool can be used to cut the rolls to the correct height. 3. For good adherence, apply uniform pressure throughout the surface area, not just the edges and corners. 4. When two edges come together from two separate pieces, overlap the dimples and seal with an adhesive band to create a continuous coverage of the wall. 5. Secure the Geo-Mat Plus to the wall with Geo-Mat accessories. 6. If the board overlaps the membrane once you have reached the grade line, a utility knife or similar tool B. When using ShockWave, install after membrane has been applied. Place and secure to substrate according to manufacturer s current written instructions. 1. While the membrane is still tacky, starting at a corner with the filter fabric side facing out-ward, install the ShockWave board horizontally over the sprayed sections of the wall. The boards should be placed side by side, extending from the top of the footers to finished grade. 2. Apply uniform pressure to the board throughout the surface area, not just the edges and corners. Note: If boards are stacked, maintain a factory-equivalent edge at all seams to ensure proper fit and drainage channel alignment. 3. The use of fasteners, such as concrete nails or Mar-flex Geo Clips, to secure the board to the walls to hold in place until backfilled is optional. 4. If using the Mar-flex Geo Clips secure the ShockWave at the top of the boards, place a Geo Clip at each corner making sure that at least two prongs from the Geo Clip is placed in each board. When securing Page 4 of 5 REV:

5 the ShockWave at the seams, place a Geo Clip in the middle of the boards making sure that there is one prong in each board. Once the Geo Clips are in place install them using a powder actuated mechanical fastener or concrete nail. 5. If the board overlaps the membrane once you have reached the grade line, a utility knife or similar tool C. When using ArmorDrain 150, install after membrane has been applied. Place and secure to substrate according to manufacturer s current written instructions. 1. While the membrane is still tacky, begin installation at a corner. Install horizontally against the waterproofing membrane with the non-woven filter fabric side facing out-ward. 2. Install panels from top of footing extending to finish grade level. If there is overlapping off the membrane once you have reached the grade line, a utility knife or similar tool can be used to cut the rolls to the correct height. 3. For good adherence, apply uniform pressure throughout the surface area, not just the edges and corners. 4. When two edges come together from two separate pieces, overlap the dimples to create a continuous coverage of the wall. 5. If needed, secure the panels to the wall using a powder actuated mechanical fastener or concrete nail. 6. If the board overlaps the membrane once you have reached the grade line, a utility knife or similar tool D. When using ArmorDrain 400 for flat decking, begin installation after membrane has been applied. Place draincore to substrate according to manufacturer s current written instructions. 1. Unroll the 400, placing gray side down against membrane. To keep in place, use double sided tape, adhesives or nails. 2. For overlaps, place adjacent sections so that the cores abut. Secure fabric overlap at five foot intervals with glue, tape or nails. 3. Join roll ends by peeling back fabric and removing 4 of core. Place end panels so that cores abut, then glue, tape or nail fabric overlap. 4. Make cuts for any drains to allow water to be drained. 5. Allow 24 hour set time. 6. Pour desired thickness of concrete over the 400. E. Protect installed insulation/drainage panels during subsequent construction. F. Backfill and Drainage 1. #57 Gravel or equivalent must go no less than 2 high at the base of the foundation and 1 in depth away from the foundation walls. 2. Adequate interior and exterior foundation drainage at the base of the foundation walls, across any floors or adjacent flower beds must be properly installed and functioning properly. 3. Backfilling should begin no sooner than 24 hours after the installation of the board, but must be backfilled within 15 days. G DrainAway Vertical Collection System Installation 1. Unroll material along foundation base; adhere to partially cured waterproofing material; use adhesive acceptable to waterproofing material manufacturer for cured waterproofing or other sheet waterproofing not requiring curing. 2. Determine the locations for the fittings that may be needed installed. Then add extra length to allow for insertion into fittings. Cut roll to needed length. 3. It is recommended that fittings be taped to the GeoDrain Tile for filter continuity. 4. Install preformed corner fittings at foundation interior and exterior corners. 5. Install outlet fittings where indicated; connect to 4 corrugated drainage pipe and run them out to a sump pump or to daylight. Note: Special care should be taken to properly compact the soil under the drainpipe 6. Leave ready for connection to corrugated drainage pipe if not present. Specifier Note: Coordinate article below with Division 1 Execution Requirements (Cleaning) Section CLEANING A. Clean spillage and soiling from adjacent construction using cleaning agents and procedures recommended by manufacturer of affected construction. Page 5 of 5 REV:
